vBe it known` that we, WILLIAM H. NIGH- oLsoN and WALTER S. ANDRE, citizens of the United States, residing at Taft, county ofj Kern, State ofCalifornia, have invented certain new and useful Improvements in Bailer Sockets; and we do declare'the following to bea full','clear, and exact `description of the same, reference being Vhad to the accom an infr` drawinfrs zand to theychai acters ofreference marked thereon`,-which form a part` of this' application'. J f

This invention relates to improvements in tools .usedin connection with well drilling, and particularlytothat classof device known as fishing tools. A Y 1 HThe principal-object of "our invention' is to produce-a tool of thisgeneral lcharacter especially intended to grip the bails of lbailers which may have been lost down'the well,though it is alsowell adapted toen gage andfgrip" any other relatively small.

V fandflatlobjects, such aspieces ofdisc-drills i i and the like.

V()thervobiects offourinvention are to l mount the gripping jaws of our toolV so that? avery firm grasp on the article being lished for will'be .automatically had, and to form the jaws so that the piece being engaged will be grippedgover'a considerable portion f of itsarea witliequal intensity and vpressure signed;

"throughout l c y ,A further `object of the invention is to produce a simple andr inexpensive device and vetone which will be exceedingly leffecti've for the purpose for which it is de- These objects wei partsas lwill `fullyl appear by a perusal of the following specification and claims-L` lnthe drawings Vsimilar characters of reference indicate corresponding part-s in the several views: t Fig. l is a vertical section of the tool. Fig. 2 is a! similar section but takenin i the lplane of the line 2 2V of Fig; 1.4

Fig. 3 is a cross section A`on line 3-3 of Fig., v

Referring now more particularly to the characters of reference onV the drawings, the numeral l denotes a stem or sha-nk threaded at its upperend as at 2 for connection to a standard rod 'or tool coupling and having an enlarged threaded portion 3 at itsV lower `along the upper portion ofthe vadjacent accomplish by means ofsuchjstructure and relative arrangement ofI Vopposed teeth being parallel both vertically A end adapted to removably screw into the Va pair of blocks 5, whose adjacent faces are flat and lie in transversely parallel planes, but are formed `with an linward slope orV taper from both ends toward their center 65 of height, as shown 6, the slope being;` symmetrical. The -boref'of the shell 4, from the lowerfends of said v'blocks to its `-lower extremity, `tapers youtwardly `as atV `7 with a slope substantially the same as that of 70 the 'block faces toformr a'flaring mouth. l To securely mountthe blocks in the shell and prevent movement thereof in any direc; tion, the faces of the y'blocks adjacent `.the shell are verticallyribbedfasat 8 for the greater portion of their height, the ribsubei ing seated in counters'unk recesses provided in the shell.- Intermediate the ends of the ribs are lugs`9 projecting outwardly "therefrom and extending tothe outside of ,the shell and fitted intosuitable sockets inthe latter. Pins 10' or `the like are driven through the shell* and llugs transversely .ofk the latter, thereby preventing inward move-V ment of the blocks. Atthe same time,fupon the` removal ofthe pins, said blocks' may beV easily removed or replaced as will' i evident. j j 4 Sli dably mounted for vertical movement sloping faces of the blocks 5 are opposed Y'jaw-blocks l1, the form of mounting em;

ploved being preferably the ordinary dovetail arrangement as shown at 12.-

The adjacent faces of the jaw blocks are provided with transversely and horizontally disposed teeth 13, exten'dimg the"full f width ofthe jaws, the adjacent edgesofthe and transversely. From f the `l'owermom", 100 teeth to the lower extremity of the jaw blocks the adjacent faces of the latter are cut V on a slope substantially parallel to the .slope of the lower portion of the corre\ sponding faces of the blocks 5, as shown at 14, and are arrangedto lie as a continue` ation of said faces Vwhen the jaws are at` their lowermost limits oftravel, as `shown in Fig. 1,

The jaw-blocks are normally held at such Q1 l l 1,546,179 Y lowermost limits by means of a compression i spring 15 mountediiithe sleeveftl above said 17, the lower end oi which rests on both-V Vblocks ll.

The shank is bored throughout as shown' l0 at 18 for the passage ot' water therethrough,

while as willv be evident', an# unobstructed pathztor thejwatei' ishadthroughoutl the re`V mainder` of the tool.

The well-bore below the tool may there- 15. fore be readily flushed out,toclearj a= piece beingtishedfor of anymud. or sand which may-surround thesame'.- i

-I-n.I operation, the tool islowered -downf the well untilY the bail or other part being 20= ishedfor passes intol the lower end of; the-r shell and is centralized relative. to the jawsv by the converging'l faces 6 ofthe 'blocks 5.

Asharp downward thrust istheir given'V to the tool, causing the bailA to bearagainstthe 2.5; jaws, the latter then automatically spread-V ing apar-t against the resistance of. the spring l5. and allowing. thebail tov pass f up between the jaw-teeth, ,Sincel the opposed kupper facesot the blocks Sionl whiclrthej aws slide 301 arel symmetrically disposed, -the jaws will move so as to-'mafiiitain their paiallelaline-V ment. relativev to eachother and to a vertical' plane..

Y bail or other flat piece being forced up between thevjaws will therefore befengaged onyits`V opposite sides with equal pressure throughout that Varea. of the piece which liesf between the Jaws,v insuringiarig-id grip on the piece.

4s., Then the tool. is raised, the jawsvwillteiid to automatically move down. andY` toward. each-other in unison and to the same extent, owing to the rigid sleeve l? resting thereonp and which. has the pressui'eof the springl 4r, bearing down-thereagainst This insuresan evenA and tir-m' grip being had on thc'fpiece being raised.- l Y Y From. thef foregoing description itwlill be readily seen: that we have producedsuch a device as substantially fulllsitheobjectsof the invention as set forth hereinaL .I Thile.thisrspecification-setsy torthin' detail.
